乳酸乳球菌KLDS4.0325产细菌素最佳培养条件的研究
Studying on the optimal bacteriocin production condition of Lactococcus lactis KLDS4.0325
摘要
Abstract
The fermentation conditions of L.lactis KLDS4.0325 isolated from self-made koumiss Xinjiang were optimized for bacteriocin production by double-plate method.The inhibitory zone diameter (mm) was used as evaluation index and quantified against Escherichia coil ATCC 25922.The result showed that the bacteriocin production reached the maximal value under the condition of 33 ℃,original pH7.0 and 120 r/min for 20 h.Further,under the optimal culture condition,the inhibitory zone diameter was 25.26 mm and the titer of bacteriocin was reached up to 5383.07 IU/mL.关键词
